Assessment of the Naso-Maxilla and Related Dentoalveolar Region with Cone Beam Computed Tomography.

Purpose: To evaluate via CBCT the anatomical variations of the maxillary teeth and associated major anatomical cavities, the maxillary sinus and nasal fossa.

Material And Methods: CBCT scans of 221 patients were used to examine maxillary sinus variations, the posterior superior alveolar artery (PSAA) course, nasal septum variations, middle and inferior concha-meatus variations, canalis sinuosus, infraorbital ethmoid cell, infraorbital canal, anterior nasal spina, and nasopalatine canal.

Results: The incidence of anatomical variations was 32.

Radiological evaluation of maxillofacial soft tissue calcifications with cone beam computed tomography and panoramic radiography.

Objective: We aimed to present the radiologic characteristics of maxillofacial soft tissue calcifications with a comparison of cone beam computed tomography (CBCT) and panoramic radiography (PR) findings.

Materials And Methods: The study was based on CBCT images obtained for different purposes between October 2017 and September 2018. The absence, location and radiological characteristics of some calcifications were evaluated in 252 patients.

The Appearance of The Infraorbital Canal and Infraorbital Ethmoid (Haller's) Cells on Panoramic Radiography of Edentulous Patients.

The aim of the study is to detect the prevalence and the characteristics of infraorbital canal and Haller's cells on panoramic radiography of edentulous patients. The study group comprised 291 panoramic radiographs of edentulous patients. Radiographs were interpreted for the visibility and characteristics of infraorbital canal and Haller's cells.

The effects of compression on the image quality of digital panoramic radiographs.

Size reduction through compression is an important issue that needs to be investigated for possible effects on image quality. The aim of the present study was to evaluate the subjective image quality of digital panoramic radiographs which were lossless and lossy compressed for the visualization of various anatomical structures. Fifty-five digital panoramic radiographs in Tagged Image File Format (Tiff) were used in the study.

Alveolar bone changes under overhanging restorations.

The aim of this study was to investigate changes in the trabecular architecture of the alveolar bone beneath overhanging restorations with bitewing radiographs in patients having no radiographically visible vertical bone loss. Twenty-eight digital bitewing radiographs with overhanging restorations and 28 digital bitewing radiographs without any restorations belonging to the contralateral side of the same patient were included in the study. Regions of interests (ROI) were created in the alveolar bone along the interproximal regions.

Osteosarcoma: a case report.

Although osteosarcoma of the head and neck is a relatively rare disease, it is a highly malignant bone tumor. Diagnosis of the tumor is important especially in early stages for improving prognosis. The patients with orofacial pain firstly prefer to go to dentists.
